Q:

# In an election only two candidates contested 20% of the voters did not vote and 120 votes were declared as invalid. The winner got 200 votes more than his opponent  thus he secured 41% votes of the total voters on the voter list. Percentage votes of the defeated candidate out of the total votes casted is:

 A) 47.5% B) 41% C) 38% D) 45%

Explanation:

Let there be x voters and k votes goes to loser then

0.8x - 120 = k + (k + 200)

k+200 = 0.41x

$\inline&space;\Rightarrow$  k = 1440

and  (k + 200) =1640

Therefore  $\inline&space;\frac{1440}{3200}\times&space;100$ = 45%

Q:

45% of 750  -  25% of 480 = ?

 A) 337.50 B) 217.50 C) 376.21 D) 120

Explanation:

Given expression = ($\inline \fn_jvn \small \frac{45}{100}$  x 750) - ($\inline \fn_jvn \small \frac{25}{100}$  x 480) = (337.50 - 120) = 217.50
